You don’t give us lot details more.
Yes, there was an AMD bug around, and some may still need the fix.
This is from an older post i saved on folder a time, you may try this, but do also some personal research.
I. AMD CPU + ONBOARD AUDIO (Realtek)
For everyone with AMD cpus who are having issues with alt-tabbing causing freezes, please do the following to eliminate the problem.
" If you have followed any of the previous workarounds posted in the forums, revert those changes. (For example restoring XAudio2_7.dll if you have removed it)
Locate your Engine.ini file, which should be found in your ConanExilesInstallPath>/ConanSandbox/Saved/Config/WindowsNoEditor/Engine.ini folder.
Example:
C:/Program Files (x86)/Steam/steamapps/common/ConanExiles/ConanSandbox/Saved/Config/WindowsNoEditor/Engine.ini
Edit it in notepad, and add the following to the end of the file:
[/script/engine.audiosettings]
bDisableMasterEQ=True
Save the file, and start the game. You should no longer experience freezes when alt tabbing.
We plan to make this an ingame client setting in a future patch.
Save the file, and start the game. You should no longer experience freezes when alt tabbing. "
Then let me say, that i run myself AMD, and alt-tab lot. My game doesn’t crash often at all, and i have very few issues compared to some players. My game is mostly very stable and doing fine.
So give a try, or post us more infos.
